Where and when was a bicycle race organized to escape to another country?

In 1915, a group of athletes from the Belgian Liege asked the commandant of the German occupation troops for permission to hold a bicycle race in order to raise funds to help the victims of the war. He agreed on the condition that each participant put a German flag on the bike.

The route of the race was assigned from Liège to the village of Molingen near the Belgian-Dutch border. At the finish line, the cyclists did not stop and went straight to the Netherlands, which was a neutral state during the First World War, and the German soldiers guarding the track did not have time to prevent the fugitives.

 Random interesting fact from the Great Encyclopedia:

How was the Witwatersrand discovered - the world's largest deposit of gold ore containing uranium?

In the entire history of mankind, about 100 thousand tons of gold have been mined on planet Earth, and half of it has been extracted from the mines of the Witwatersrand in South Africa. Sometimes more than a thousand tons of precious metal were mined here in a year. And this unique deposit was discovered quite by accident.

In 1886, the farmer Walker, who lived near the city of Johannesburg, noticed a stone with brass-colored sparkles. I decided, just in case, to crush the rock and wash the sand in a basin of water. As is often the case with new gold prospectors, Walker was wrong: the brassy grains weren't gold. It was the mineral pyrite, an iron sulfide of little value. But besides pyrite, at the bottom of the basin with washed crushed rock, there was a thin bright yellow strip of real golden sand!

Thus was discovered the gold of the Witwatersrand, the world's greatest accumulation of precious metal. Subsequently, it turned out that uranium is also concentrated here, along with gold. Thus, the value of the deposit has increased even more.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Anti-clot magnet 28.04.2015

Usually, to remove a blood clot, the tPA protein, a tissue plasminogen activator, is injected into the blood vessel. This substance is normally present in the blood, contributing to the destruction of fibrin fibers. Thus, its addition increases the rate of resorption of blood clots.

However, the dose introduced into the vessel is quickly distributed throughout the circulatory system, and only a small part of the thrombus reaches it. It would seem that you need to increase the dose, but if you overdo it, bleeding may occur.

A safe alternative is offered by researchers from the Houston Methodist Research Institute, led by Dr. Paolo Desuzzi. They were able to pack the tPA protein, together with magnetic iron oxide nanoparticles, into a shell of another blood protein, albumin. This package provides a triple advantage.

Firstly, it is easy to concentrate magnetic particles exactly at the site of thrombus formation.

Secondly, they can be heated by an alternating field - it has been noticed that tPA works most actively at temperatures above 40°C, and, of course, it would be better to create such a temperature only in a small area of ​​the body.

And thirdly, the albumin shell masks the contents from the immune system, and a margin of time is obtained for which the drug will have time to get to the blood clot.

As a result, in experimental mice, the rate of resorption of blood clots increased a hundred times, and when heated - a thousand times compared with the introduction of a "naked" plasminogen activator. Since iron oxide is already approved for use as a contrast agent in CT scans, and tPA with albumin is already present in the blood, the researchers hope to move quickly to human trials of the new drug. The doctors are looking forward to it.
